Bioenergy crops in marginal lands have been always a focus of attention for researchers, bioenergy companies and governments. But those areas would clearly have lower yields. Are lower cost feasible in those regions?.

The sustainable use of energy crops for biogas is a possible solution to reduce the contribution to climate change of human activities. Power based on biomass, in particular biogas, is increasing, with a concomitant increase in the need for energy crop production.

Several experiences have been providing evidences on the feasibility of marginal lands bioenergy. We selected promising alternatives for biofuels, heat and electricity in semiarid environments, abandoned lands and low competitive regions.
